The ABB S273-K2A is a 2 A K-curve miniature circuit breaker (MCB) designed for DIN rail mounting in distribution panels and control cabinets. Its K-curve trip characteristic (10–14× In) makes it suited for motor and inductive load circuits where brief inrush currents must not cause nuisance tripping — typical for pump, fan, and compressor branch protection.
